* Iberia to cut 3,807 jobs in deep restructuring plan
* Starts 30-day negotiating process with unions
* Unions ready for 15 days of strikes in February and March
MADRID, Feb 12 (Reuters) - Spanish airline Iberia pressed ahead with its job cuts plan on Tuesday, saying it was now aiming for 3,807 redundancies, despite a threat by unions to take strike action later this month.
Iberia, part of the International Airline Group, has said the job reductions are necessary to allow the loss-making airline to return to growth.
The job cuts will comply with Spanish labour laws, Iberia said in a statement, which allow pay-offs of only a year's salary.
Iberia had originally planned to axe 4,500 jobs, a quarter of its workforce, but later presented unions with a plan for 30 percent fewer reductions. Unions rejected the proposal and called for strikes over 15 days between February and March.
The plan for the job reductions will now undergo a formal 30-day consultation process with unions, Iberia said.
